Modeling the gas-phase chemistry of the transitional disk around HD 141569A.

JONKHEID B., KAMP I., AUGEREAU J.-C. and VAN DISHOECK E.F.

Abstract (from CDS):

The chemistry, distribution and mass of the gas in the transitional disk around the 5 Myr old B9.5 V star HD 141569A are constrained.A quasi 2-dimensional (2D) chemistry code for photon dominated regions (PDR) is used to calculate the chemistry and gas temperatures in the disk. The calculations are performed for several gas distributions, PAH abundances and values of the total gas mass. The resulting CO J=2-1 and J=3-2 emission lines are computed with a 2D radiative transfer code and are compared to observations.The CO abundance is very sensitive to the total disk mass because the disk is in a regime where self-shielding just sets in. The observed CO emission lines are best fit by a power-law gas distribution of 80M⊕ starting at 80AU from the central star, indicating that there is some gas in the inner hole. Predictions are made for intensities of atomic fine-structure lines. [CI], which is the dominant form of carbon in large parts of the disk, is found to be a good alternative tracer of the gas mass.
